MediaTek iommu arranges dma ranges for all the masters, this patch is to
help them set dma mask. This is to avoid each master setting their own
mask, but also to avoid a real issue, such as JPEG uses
"mediatek,mtk-jpgenc" for 2701/8183/8186/8188, then JPEG could ignore its
different dma_mask in different SoC to achieve common code.
